Design industrial refrigeration systems and select components

Assessment tool

Version 1.0
Issue Date: May 2024


This unit involves the skills and knowledge required to design industrial refrigeration systems and select components.

It includes applying processes and methods of refrigeration and food storage technology, industrial refrigeration system components and piping, safety and relevant industry standards. It also includes following design specifications and customer requirements, and documenting system designs.

The skills and knowledge described in this unit may, in some jurisdictions, require a licence or permit to practice in the workplace subject to regulations for undertaking refrigeration and air conditioning work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.

No other licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least one occasion and include:

understanding required operating functions and parameters from the design specification

developing the design within the safety, regulatory and functional requirements and budget limitations

documenting and presenting design effectively,

successfully negotiating design alteration requests

obtaining approval for final design

dealing with unplanned events

applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements, including using risk control measures

designing industrial refrigeration systems

preparing to design industrial refrigeration systems.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of:

required mass flow rate of refrigerant and volume flow rate at various points in system

theoretical compressor power

required condenser capacity

major system components:

refrigerants, including R717 and R22

secondary refrigerants

component lubricant refrigerant compatibility

evaporators

condensers and cooling towers

compressors

expansion valves

interconnecting piping and

isolating valves

pilot-operated valves

refrigerant accumulators and liquid pumps

problem-solving techniques

relevant job safety assessments or risk mitigation processes

relevant manufacturer specifications

relevant WHS/OHS legislated requirements

relevant workplace budget, quality, policies and procedures

relevant workplace documentation.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or simulations

relevant and appropriate materials, tools, facilities and equipment currently used in industry

applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.

Designing industrial refrigeration systems must include at least the following:

two different industrial systems with one of the following:

condenser

compressor

evaporator

associated components and controls

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
